General Description
The A62S9308 is a low operating current 4,194,304-bit
static random access memory organized as 524,288
words by 8 bits and operates on a low power supply
voltage from 2.7V to 3.6V.
Inputs and three-state outputs are TTL compatible and
allow for direct interfacing with common system bus
structures.
Two chip enable inputs for Mini BGA package are
provided for power down and a device enable and an
output enable input are included for easy interfacing.
Data retention is guaranteed at a power supply voltage
as low as 2V.
